Apartment Therapy is having a Smallest, Coolest Apartment Contest. They are trying to find the most beautifully and creatively decorated apartments that are smaller than 650 sq feet (60 sq meters). They go from classy to eclectic and all of them use those tiny spaces amazingly well. Don't forget to scroll down, each entry ends with a floor plan for the space.
Even if you aren't interested in decorating, it's always fun to be nosey and poke around in other people's stuff.
